From their earliest evolution to the invention of the "horseless carriage," this picture book captures how-for much of human history-horses powered the world! For thousands of years, horses and humans lived, worked, and played together, side by side. From the time they were first domesticated to the invention of the wheel, saddle, bit, and bridle; horses brought far-flung lands closer together at the speed of a gallop. Trade, agriculture, transportation, and more were expanded in new ways-all made possible by the power of the horse. In dazzling spreads packed with maps, sidebars, and other hidden gems, explore the special connection between horses and humans. Discover how horses evolved and track their migration as they come to live on six continents. See the everyday jobs done by horses for centuries. And consider the profound changes that came about when gasoline-powered engines arrived on the scene. An encyclopedic look at this magnificent animal, Horse Power offers a unique view of world history from the ancient past to today.
